Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Biodegradable magnesium alloys are limited in orthopedic applications due to their rapid corrosion and poor interfacial stability. In this work, a composite coating is constructed via magnetic filtered cathodic vacuum arc (MFCVA) deposition of a Zn interlayer, followed by hydrothermal in situ generation of ZnO to induce hydroxyapatite (HA ...

, 2013 本发明提供一种非球形水凝胶微颗粒合成的方法，第一级采用T-通道结构形成水包油的液滴，第二级采用流动聚焦结构形成油/水/油的双乳液。在紫外光照下，双乳液中间相聚合形成水凝胶微颗粒，外相和中间相界面的聚合反应被抑制，导致水凝胶未能包裹内相油核，形成了以内相油核为模板的水凝胶微颗粒。本发明的优点在于通过控制内相和中间相的体积流速比，形成一系列具有相似形貌的水凝胶微颗粒；通过控制单个双乳液内核的数目，形成了弯月形、多足形等不同形貌的水凝胶微颗粒；通过控制单体溶液内的添加物，形成了具有特殊功能的水凝胶微颗粒（荧光、

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Fe‐N‐C electrocatalysts are considered promising alternatives to platinum‐based catalysts for advancing the development of metal–air batteries. However, the simultaneous realization of scalable synthesis, hierarchical mass‐transfer pathways, and precise regulation of Fe‐N4 sites remains challenging. Different from conventional Fe‐N‐C synthesis,

GHK‐Cu Delays Aging Through the Repair of Mitochondrial Dysfunction
Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Althugh glycyl‐L‐histidyl‐L‐lysine copper (GHK‐Cu) shows antiaging potential, its precise molecular mechanisms remain unclear. Using Caenorhabditis elegans (C. elegans) as an in vivo aging model, we observed that GHK‐Cu extended organismal lifespan and improved stress resilience.
